PILE.

SPECIFICATION forming part Of Letters Patent NO. 226,237, dated April 6,1880,

' Application filed January 24, 1880.

To all whom it may concern:

Be it known that I, ISAAC W. MACLAY, of Metuchen, in the county ofMiddlesex and State of New Jersey, have invented a new and usefulImprovement in Iron Piles, which improvement is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings.

The object of my invention is to prevent water rising through the bottomof iron tubular piles after being sunk by the waterjet process andlessen the corrosion of the inner surface of the piles. This Iaccomplish by closing the bottom of the pile, after it is placed inposition, by the use of an iron plug or stopper of nearly the samediameter as the interior of the pile, fitted or shaped to partly enterand rest in the conical opening of the disk or shoe at the base of thepile.

In the drawings, Figure 1 is a cross-section 20 of the pile A, the shoeB, and stopper G. Fig. 2 is a View of the same.

The stopper G is lowered through the hollow pile by means of anattachment to the ears g g of the stopper until it rests at the foot of25 the pile, where it is secured by concrete or cementinserted in thepile.

I claim as my invention- The combination of the iron plug with thetubular iron pile, substantially as described, 30 for closing theaperture at the bottom of the pile, as and for the purpose set forth.
